Aerospace Grade Aluminum with a touch of Titanium These pens are made using lightweight 6061 aerospace aluminum and solid titanium for the clip. We feel this combination of materials deserved a new periodic element symbol, so we gave it one and laser engraved "Ai" on every pen clip. The "A" is from the first letter of the aluminum periodic symbol and the small "i" was chosen from the titanium element Ti to represent the touch of titanium.
